ATTACHMENT FOR PLANTERS.

Specification of Letters Patent.

Patented Jan. 21, 1913.

Application filed May 29, 1912. Serial No. 700,368.

To aZZ whom it may concern Be it known that I, ADOLPH J. ANDERSON, acitizen of the United States, residing at Houston, in the county ofHouston and State of Minnesota, have invented certain new and usefulImprovements in Attachments for Planters; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to planters and has for its especial object toprovide an attachment for cooperation with the furrow opener thereof.

The purpose of the improved attachment is to smooth the furrow as it isopened up by the furrow opening blade, to brush aside all obstacles suchas stones, sod, and corn. stalks, and to regulate the depth of thefurrow to insure the planting of drop seeds at a properand uniformdepth.

Particularly my invention is in the nature of an improvement on my twoprior U. S. patents identified as follows, towit: No. 941,485, issued ofdate November 30, 1909, entitled Corn planter and No. 984,731, issued ofdate February 21, 1911, entitled Attachment for planting, and providesbetter means for adjustably and detachably connecting the so-called shoewings to planters of different makes wherein the furrow opening bladesand seed boots are of difierent sizes and form.

To the above ends, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Referring to the drawings,-Figure 1 is a plan view of the improvedattachment applied in working position to the furrow opening blade andsee-d boot of the planter, some parts of which are shown in section;Fig. 2 is a side elevation of the parts shown in Fig. 1; Fig. 3 is aview corresponding to Fig. 1 but showing diflerent means for supportingthe improved attachment; and Fig. 4 is an inside side elevation of oneof the so-called shoe wings with some parts of the supporting framesectioned on the line 00 w of Fig. 3, the furrow opening blade and seedboot being indicated by dotted lines.

The planter shoe comprises a forwardly and upwardly curved furrowopening blade 1 cut away at the rear end portion of its cutting surface,as indicated by the numeral 2. Rigidly secured to the rear upper surfaceof the furrow opening blade 1, directly over the cut away portion 2, isan upwardly extended seed boot 3. The furrow opening blade 1 and seedboot 2 are secured to a suitable supporting frame 4, only a portion ofwhich is shown in Figs. 3 and 4. The parts thus far described may be ofthe standard or any suit-able construction.

The improved attachment is in the form of a pair of shoe wings 5terminating at their front ends in flat upwardly extended convergingportions 6 which engage and are pressed against the forwardly upturnedportion of the furrow opening blade 1. The outeredges of the convergingportions 6 are inclined outwardly and upwardly along linesintermediately between the front and rear edges of the upwardly curvedfurrow opening blade 1, as best shown in Fig. 2. These edges are alsobeveled so that they lie flat on the sides of the furrow opening blade1, as shown in Figs. 1 and 3. From the lower edges of the convergingportions 6, the shoe wings 5 terminate in rearwardly diverging flatsurfaces 7, the outer edges of which are outwardly and upwardly curvedto form vertically inclined side flanges 8. These side flanges formcontinuations of the converging portions 6 and diverge rearwardlytherefrom.

Referring to the means illustrated in Figs. 1 and 2 for supporting theshoe wings 5, the numeral 9 indicates a pair of heavy supporting barsthat are rigidly secured, at their forward ends, to the upper innerfaces of the side flanges 8 intermediately between the ends thereof, bymeans of rivets 10. From their forward connected ends, the bars 9 firstconverge upwardly and rearwardly and then extend parallel in ahorizontal rearward direction and embrace the seed boot 3. At their freerear ends, the bars 9 extend slightly beyond the seed boot 3 and aredetachably connected by means of a horizontally ext-ended draw bolt 11.Slidably mounted on the bars 9, in advance of the seed boot 3, is a clip12 comprising a yoke 13 having slidably mounted on its prongs a clampingbar 14. The yoke 13 and bar 14 embrace the bars 9 and are frictionallyclamped thereon by means of nuts 15 having screw threaded engagementwith the ends of the prongs of the yoke 13. As is evident, the draw bolt11 and clip 12 frictionally and adjustably clamp the bars 9 onto theseed boot 3 and thereby support the shoe wings 5 in their properrelation to the furrow opening blade 1 and are entirely free therefrom.By moving the bars 9: up or down on the seed boot 3, the positions ofthe shoe wings 5 may be changed, at will, to vary the depth of thefurrow. It is also evident that the clip 12 can be slid horizontally onthe bars 9 toward and from the draw bolt 11 thereby making the improvedattachment adjustable to planters having seed boots of different sizes.And by adjusting the draw bolt 11 and the clip 12 with respect to eachother, the angularity of the bars 9 can be varied to force theconverging portions 6 of the shoe wings 5 onto the furrow opening blade1, irrespective of its thickness.

Referring now to the construction shown in Figs. 3 and 4 of thedrawings, the only difference from that shown in Figs. 1 and 2 is in themeans for supporting the shoe wings 5. In this construction, each shoewing 5 is independently suspended from the supporting frame 4 by meansof a U-shaped bar 16. The intermediate portions of these bars 16 extendhorizontally in the direction of the travel of the machine and arerigidly secured to the fiat surfaces 7, of the wings 5, by means ofrivets 17. At their upper ends the bars 16 are detachably secured to thesupporting frame 4, by means of clips 18 of substantially the same formas the clip 12. In this construction, the converging portions 6, of theshoe wings 5 are preferably connected, as shown, by means of ahorizontally extended draw bolt 19 passed over and resting upon theupper edge of the furrow opening blade 1.

What I claim is 1. In a planter, the combination with a furrowopenerhaving a forwardly extended upturned portion, of a pair of shoewings having forwardly converging portions engagingthe sides of theupturned portion ofsaid furrow opener, and common means entirelyindependent from the furrow opener supporting said shoe wings inoperative positions with respect to said furrow opener, and which meansis adjustable for moving the forwardly converging portions of said shoewings toward and from each other, substantially asdescribed.

2. In a planter, the combination with a furrow opener having a forwardlyextended upturned portion, of a pair of shoe wings having forwardlyconverging portions engaging the sides of the upturned portion of saidfurrow opener, a pair of supporting bars rigidly secured, one to each ofsaid shoe wings, and means for adjusting said bars to positively movethe forward converging portions of said shoe wings toward and from eachother, substantially as described.

3. In a planter, the combination with a furrow opener and a seed bootrigidly secured thereto, said furrow opener having a forwardly extendedupturned portion, of a pair of shoe wings having forwardly con-- vergingportions engaging the sides of the upturned port-ion of said furrowopener, a pair of rearwar'dly extended supporting bars rigidly securedat their forward ends, one to each of said wings, and at their rear endsembracing said seed boot, and a draw bolt and a clip connecting saidsupporting bar at the front and rear of said seed boot and adapted tofrictionally and adjustably clamp said bars onto said seed boot, saidclip being adjustably mounted on said bars for movement toward and fromthe seed boot, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
